JavaScript has definitely been among the most influential technologies for almost a decade now. A lot of this is due to the sophisticated JavaScript VMs in modern browsers, Node.js and Electron. In this talk we’re going to explore important ingredients of these modern JavaScript VMs, specifically how ChakraCore, the engine that powers Microsoft Edge, and V8, the engine that powers Google Chrome, compare to each other for certain key features.

This talk is superb. Mathias and Benedikt are the best teachers when it comes to demystifying the complex topic.

Your explanation of inline caching was amazing! Thank you for this gem!

It amazes me how doing something as simple as making sure your objects have the same shape, even if it is empty, can make a significant impact on performance. Excellent presentation, I think I will have to to a look at some code and see if I can make some improvements to some code I have been working with lately.

@abhishekmehandiratta4241 15 часов назад

is the property lookup not constant time when accessed for the first time? (probably yes because we have to traverse the transition states of shape object) since there are offsets in the property metadata, it means that there is an inherent ordering in the properties.. i.e. for object {x: 1, y: 2, z: 3} - we will have x at offset 0, y at offset 1, and z at offset 2. But now if we have an object {y: 1, z: 2, x: 3} - does this share the same shape transition tree or is it different?

The JavaScript language is a kitten killer

@dmitriyzakharov4740 6 лет назад

Thx!

@sasuke_2145 4 года назад

what data structure do they use to store shapes and actual values???

@Neehize 2 года назад

Okay but how does it kill the kitten and how do we know if it kills an entire kitten family or not this I don't get 🤔 If the array has 1 index it kills 1 kitten and if it has more than 1 it kills a family?

@Luxcium 4 года назад

Can we (only for fun) do all that stuff that we should not do in JavaScript (without killing a kitten) in a kind of fantasy land (not related to functional programming just using same name to describe something else)
